Dilakukan skrining talasemia dan Hb varian pada keseluruhan sampel, yang meliputi pemeriksaan hitung sel darah lengkap, analisis Hb metode HPLC dan analisis DNA untuk deteksi pembawa sifat talasemia α. Uji kualitas darah simpan dilakukan melalui penghitungan persen hemolisis sel darah merah pada...

Role of staphylococcal phage and SaPI integrase in intra- and interspecies SaPI transfer.

SaPIbov2 is a member of the SaPI family of staphylococcal pathogenicity islands and is very closely related to SaPIbov1. Typically, certain temperate phages can induce excision and replication of one or more of these islands and can package them into special small phage-like particles commensurate with their genome sizes (referred to as the excision-replication-packaging [ERP] cycle). We have s...

SaPI operon I is required for SaPI packaging and is controlled by LexA.

Transfer of Staphylococcus aureus pathogenicity islands (SaPIs) is directly controlled by the cellular repressor LexA. We have found that transcription of the SaPIbov1 operon I is repressed by LexA and is therefore SOS-induced. Two copies of the LexA binding site consensus (Cheo box) are present in the 5' region of this operon, at the same location in all of 15 different SaPIs analysed. Both of...

Hormon wzrostu a proces starzenia się

Studies in mutant, gene knock-out and transgenic mice have demonstrated that growth hormone (GH) signalling has a major impact on ageing and longevity. Growth hormone-resistant and GH-deficient animals live much longer than their normal siblings, while transgenic mice overexpressing GH are short lived. Actions of GH in juvenile animals appear to be particularly important for life extension and ...
